ACETYLENE-GAS LAMP.

Specification of Letters Patent.

. Patented June 20, 1916.

Application filed April 16, 1915. Serial No. 21,902.

To all whom it may concern:

Be it known that I, ANTHONY Mnssma, a subject of the King of Italy, a resident of Benld, in the county of Macoupin, State of Illinois, have invented certain new and useful Improvements in Acetylene-Gas Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a. part of this specification.

My invention relates to acetylene gas lamps and has for its object to provide a filter in communication with the gas conducting pipe which does not readily become damp and clogged, and to provide a reflector removably attached to the gas conducting pipe, the said reflector having a removable frangible burner secured thereto so that the reflector and burner may be handled to gether in removing and attaching them, thereby avoiding breakage of the burner.

Figure I is a side elevation, partly in section, of a miners lamp embodying the features of my invention. Fig. II is a vertical section of the lamp. Fig. III is a horizontal section taken approximately on the line III-III, Fig. II.

A designates a water receptacle having a bottom wall 1 and provided with a screw threaded neck 2.

B designates a carbid receptacle having a neck 3 at its upper end which is screwed into the neck of the water receptacle. A water tube 5 passing through the water receptacle A and bottom wall 1 extends into the carbid receptacle. This water tube is provided with an inlet port 6 adjacent to the bottom wall 1 so as to permit the escape of water from the lower portion of the water receptacle.

7 designates a valve member in the form of a rod having a tapered valve seat 8, near its lower end, adapted to engage the tapered lower portion of the water tube 5 to prevent the escape of water into the carbid receptacle except as needed. The upper portion of the valve member 7 is screwed into the upper portion of the water tube. The screw threaded valve member 7 is provided with an operating handle 9 at its upper end. The valve member may be moved toward and away from the lower end of the water tube by rotating the handle 9.

l0 designates a cap screwed onto the upper end of the water tube 5, and 11 designates packing arranged between said cap and tube.

The lower end of the valve member '7 is provided with a reduced extension 7 which passes through'the reduced lower end of the water tube so as to serve as means for cleaning the tube at this point.

12 designates a gas conducting tube ex tending from an opening in the bottom wall of the water receptacle to an opening in a side wall thereof, said conducting tube being provided. with a pocket member 13 at its outer end.

14 designates a reflector having a neck screwed onto the pocket member 13 and provided with a sleeve for a removable frangible clay tip or burner 15. A gasket 16 is arranged between the pocket member 13 and the reflector 14.

17 designates cotton or other suitable filtering material, arranged in the pocket member 13 so as to filter the gas immediately be fore it reaches the burner 15. By filtering the gas immediately before it reaches the burner I prevent the carbid dust and other matter, which accumulates in the pipe 12, from passing into the small discharge port in the burner. Another advantage of this structure is that the filtering material may be readily removed and replaced by simply unscrewing the reflector from the pocket member 13.

20 designates a tube for conducting gas from the carbid receptacle to the upper portion of the water receptacle. This tube passes entirely through the water receptacle and its lower end is located in the carbid receptacle.

21 designates a discharge port, formed in the upper portion of tube 20 to permit the discharge of gas near the top wall of the water receptacle. The tube 20 is fixed to the screw threaded member 22, the latterbeing fixed tothe top wall of the water receptacle.

23 designates a cap screwed onto the upper end of the threaded member 22 to prevent the escape of gas. A scraper 24, passing through the tube 20, is fixed to the cap 23. This scraper 24 is preferably a flexible spiral member adapted to be rotated in the tube 20. The cap 23 may be readily unscrewed and removed with the result of rotating and sliding the scraper in the tube 20, thereby removingQcarbid andother' matter from said tubef Thewater receptacle is preferably' made airtight or water tight so as to prevent the escape of water to the exterior of the lamp. When the device is in service the gas flows through the tube and into the upper por-' tion of the water receptacle to compensate for the displacement of the water and the pressure of this gas is utilized to force the water into the cal-bid receptacle.

designates ribs pressed from the carbid receptacle to serve as hand grips in securing the carbid receptacle in the threaded neck of the water receptacle.

26 designates a tube extending from the top wall of the water receptacle, and 27 is a substituted for the tip or burner removed.

I claim 1- w 'An acetylene gas lamp comprising a removable refiector having a tip or burner sleeve and a removable frangible clay tip or burner secured ,in the said tip or burner;

sleeve. 7
